MULTI-POLAR BRUSHLESS GENERATOR FOR SUPPLYING ELECTRICAL ENERGY TO RAILWAY PASSENGER CARS

摘要

The invention relates to electrical engineering industry, in particular, to electrical machinery, and can be used as an electrical energy source for ensuring railway passenger cars with electrical energy. The offered multi-polar brushless generator comprises a windingless toothed rotor (1), a toothed stator (2), which teeth (3) are embraced by armature winding coils (4), being electrically connected with excitation winding, and a rectifier (6) being connected with the armature winding coils (4), wherein the armature winding coils (4) are connected in series-opposite connection, forming an integer k series connection of an open hexagons or 2k open triangles so as the number of armature winding coils (4) nk and the number of the corresponding stator teeth (3) Z1 is determined by the number,n k =Z1=6k wherein the open polygon chain forming terminals are excitation inputs, and hexagon vertices - outputs for outgoing alternating current load, which is supplied to the rectifier (6), containing 1+kn branches, to which middle points vertices of the hexagons are connected. Owing to the specific arrangement of the coils the alternating current does not exert negative influence on the direct current and vice versa. Combining the armature and excitation coils makes it possible to simplify the equipment device, to raise its reliability, and to reduce its weight, especially that of copper, i.e. to considerably improve the efficiency of the offered technical solution.
